Ex-cop Gerno Blaicher's wife is fatally shot, days before his retirement, with his service gun, which he claims to be stolen years ago during his arrest of money shipment robber Karl-Heinz Wellbrecht, the loot also remains missing. Magda Blaicher had an affair with fellow cop Fonsi Höller. Nobody confesses. The missing gun is used to shoot at detective Torsten Voß's car while he drives with Marie. Although no link to the case is known, chief Achtziger orders Voß to a safe 'house' mountain cabin, where Marie joins him, with a surprise result.
